Understanding High-Level Design Concepts
High-Level Design (HLD) refers to the structure of a system that will be used to create a product. The HLD provides a clear overview of the entire system and lists the primary elements that will be designed for the product. It is crucial to identify the components that are necessary to develop the product. By doing so, designers can create a plan that is both practical and effective. Additionally, the HLD helps individuals who are not directly involved in the design process to understand the project’s scope and objectives.The Purpose of High-Level Design (HLD)
The purpose of the HLD is to provide designers with a comprehensive plan for creating the system. It outlines the project’s scope, objectives, and constraints. It also helps to identify the resources that will be required to complete the project. With a well-planned HLD, designers can develop a product that meets all requirements, is user-friendly, and functions correctly.Components of High-Level Design
The HLD includes several components, including:- Primary Elements: These are the essential components required to build the product. They are the building blocks that will be used to create the entire system.
- Interfaces: These are the connections between the primary elements. They allow the product to function as a whole.
- Architecture Diagram: This diagram provides an overview of the entire system. It lists the primary elements and interfaces and shows how they are connected.
- Constraints: These are limitations that may impact the product’s design, development, and performance. Identifying constraints early in the process helps to avoid issues later on.
- Scope: This outlines the project’s objectives, timeline, and budget. It helps to ensure that all project stakeholders are on the same page.
